This means that our delay increment (in ms) = tan 30º x 0.572 x 1000
340
= 0.577 x 0.572 x 2.94
= 0.97mS or 970uS.
The following delay line taps would be required for the above system:
t0 = 0ms
t1 = 0.97mS
t2 = 1.94mS
t3 = 2.91mS
t4 = 3.88mS
t5 = 4.85mS
t6 = 5.82mS

It is possible to apply electronic shaping to horizontal arrays. For instance, it is
common to use curved main clusters for smooth mid and high frequency coverage.
Ground-based subwoofer arrays should follow the same curvature to maintain mid-
bass crossover coherence but this is often difficult due to flat-fronted stage structures.
The following illustration shows an example of a flat-fronted horizontal array
electronically splayed to emulate the greyed-out example shown.
